TF and breast carcinoma: This experimental approach resulted in the identification of several previously unappreciated genes, whose expression can be regulated by Snail1, and furthermore, it functionally established that removal of a major EMT‐TF from the triple‐negative breast cancer cells showed significant repression of cell motility (Fig. 5); however, it was sufficient to induce only partial or weak signs of reversion to a more epithelial phenotype, reflecting an intermediate phenotype of cell differentiation (Fig. 5).
